Adobe Town/Salt Wells Creek Wild Horse Gather EA Available

The Bureau of Land Management (BLM) Rawlins and Rock Springs field offices are launching a 30-day public comment period on an environmental assessment (EA) to gather excess wild horses from the Adobe Town and Salt Wells Creek (ATSW) Herd Management Areas (HMAs).

The two HMAs are managed collectively as the ATSW Complex due to wild horse movement between the two areas. The Complex is located in the checkerboard pattern of mixed public, private, and state land ownership in Sweetwater and Carbon counties, stretching from Interstate 80 south to the Wyoming/Colorado border. The BLM respects private land owner rights while managing wild horse populations. The ATSW Complex includes approximately 510,308 acres which are privately held. This gather would reduce landowner conflicts where the wild horses stray onto private lands.

Population surveys conducted in May 2012 found approximately 1,005 wild horses in the ATSW Complex. However, wild horse populations are expected to increase by approximately 20 percent with the 2012 and 2013 foaling seasons, bringing the population in the ATSW Complex to an estimated 1,447 wild horses by summer.

The appropriate management level (AML) for the ATSW Complex is 861-1,165 wild horses. The gather is necessary to maintain the wild horse herds toward the lower range of the established AMLs in compliance with the 1971 Wild Free-Roaming Horse and Burro Act, and the 2003 Wyoming Consent Decree. The AML for the ATSW Complex was established through an agreement with private land owners and wild horse advocacy groups. It was confirmed in the 1997 Green River Resource Management Plan (RMP) and through the 2008 Approved Rawlins RMP. The proposed gather is anticipated in 2013.

The proposed action in the EA is also in conformance with the Consent Decree with the Rock Springs Grazing Association (RSGA) ordered by the U.S. District Court on April 3, 2013, to remove all wild horses from private lands within the checkerboard portion of the ATSW Complex in 2013. According to the Consent Decree, if the numbers are likely to exceed 200 wild horses within the checkerboard portion of the ATSW Complex, the BLM shall prepare to remove the wild horses from the private lands.

The ATSW Complex was last gathered in fall 2010. During that gather, 99 mares released back to the HMAs were administered the PZP fertility control vaccine. Fertility control is an alternative being considered in the EA.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to manage and conserve the public lands for the use and enjoyment of present and future generations under our mandate of multiple-use and sustained yield. In Fiscal Year 2014, the BLM generated $5.2 billion in receipts from public lands.
